Gear train
A gear train is assembled from three gear wheels. The first has 165 teeth, the second 132 teeth, and the third 231, where the second engages with the first and the third with the second. The first and third do not touch. How many times per minute will all three wheels be in the same relative position as at the start, if the smallest wheel makes 2600 revolutions per minute? How many revolutions will the largest wheel make?
